The inspiration came from wanting to do a sequel to the opera of  Mme Butterfly by Puccini. Although the idea was quickly dropped, it became obvious that the core of the project would be the theme of love and how one can pass through many different kinds of love in life. There is no story and almost no words in this project but mostly abstract sound and images that try to express three main types of love: Éros, Philia, and Agapè.

The writing for voice is particular and a bit unnatural since it is influenced by typical synthesizer technics (filters, octave shift, tremolo, etc.). Also, the piece is specifically written for the performers who created it and not for a conventional SATB 4 part ensemble, although the performer roughly corresponds to those voice types. This explains some extreme writing for the voice such as many high notes for the "soprano", an extremely wide range for the "alto", many vocal experimentations for the "tenor" and extreme profound notes for the "bass".

The few lyrics featured in this work include some quotations from the libretto of Mme Butterfly by L. Illica and G. Giacosa, some original text written by the composer, and a traditional French song titled "Oh Ursule".
